Kraft lignin hydrogels have been synthesized through a
simple, green and energy-saving process in the presence of
a cross-linking agent, polyethylene glycol diglycidyl ether
(PEGDGE), and fully characterized. The hydrogels can be
used to entrap active compounds, during the synthesis
process, for controlled release purposes, or they can be
employed in the removal of water pollutants. Preliminary
adsorption tests, carried out with methylene blue, showed
excellent results
